Claims (10)

  1. Aktiv geräuschunterdrückender Ohrhörer, umfassend:
    einen Ohrstöpsel (5), der so konfiguriert ist, dass er zumindest teilweise in einem äußeren Gehörgang getragen werden kann, wobei der Ohrstöpsel (5) einen Endbereich (6) an einem Ohrende des Ohrstöpsels (5);
    einen Lautsprecher (1);
    ein Frontvolumen (2), das in einer Schallausbreitungsrichtung an den Lautsprecher (1) angrenzt, wobei das Frontvolumen (2) mit dem Endbereich (6) gekoppelt ist, oder das Frontvolumen (2) mit einem Lautsprecherkanal (10) gekoppelt ist, der seinerseits mit dem Endbereich (6) verbunden ist;
    ein Mikrofon (11) einer aktiven Geräuschunterdrückungsschaltung (ANC), die so konfiguriert ist, dass sie an den Lautsprecher (1) ausgibt,
    dadurch gekennzeichnet, dass
    ein Kanal (7), der ein verbindender akustischer Kanal ist, den Endbereich mit einem zusätzlichen Volumen (3) koppelt, das innerhalb des Kopfhörers ausgebildet ist, und für eine Tiefpass-Charakteristik sorgt und die Betriebsstabilität des ANC-Systems verbessert.
  2. Aktiv geräuschunterdrückender Ohrhörer nach Anspruch 1, wobei der Kanal (7) durch einen Kanalmantel definiert ist, der entlang seiner Oberfläche in Bezug auf das Frontvolumen (2) und/oder den Lautsprecherkanal (10) akustisch isoliert ist, wenn er an den Kanal (7) angrenzt.
